Hello Maya,
While I can't speak to any best practices or regulatory considerations, I would recommend utilizing a set of cloud Edges within the org. This will handle the call routing, media, text-to-speech, AI capabilities, etc. I would recommend taking a look at this article in the Resource Center to get a take a look at some of the initial start up steps.
If you haven't done so already, I would recommend reaching out via the contact form. They should be able to help address your questions. Hopefully we can hear from the Community as well with their own experiences deploying in the region.
